Interview Questions

Kay T. - "How I would approach this question: Understand the goal of the customer service platform: What is the main business goal of this company and how is the customer service platform serving the company goals? For this question, I'm assuming the user journey is that customers come to the customer service platform when they run into issues. Thus, ultimately the customer service platform is feeding into the top line business metric of customer retention. Do customers keep"See full answer

Sankar S. - "We will not always have all the required data to make a decision quickly. We need to work with ambiguity effectively by tying up the available facts with intuition."See full answer

M D. - "Understand the business problem: Identify the business problem that the AI data product is intended to solve. Identify the target audience: Understand who will be using the data and what problem they will be solving for using the data. This will inform the features and functionality that should be included in the product.

A G. - "Clarification Qs: What does "split" mean here? - split the UI and if so how (through tabs?) What counts as "media" - clarified already What is prompting us to consider this change? - any negative feedback from the users/ decrease in certain Newsfeed metrics like engagement etc/ any particular business goal? is this across or platforms eg desktop/mobile ? Is this for all regions? Mission of FB: Fb's mission is to bring people closer together by enabling them to build communiti"See full answer

Nikita G. - "Thanks for the question. The way I would like to proceed with this question is firstly, to get more context about the problem by asking some clarifying questions and narrowing the scope. Then, I would like to break the problem into smaller components to understand where exactly our problem lies. Then make a user journey for that particular area and identify the technical and non-technical factors which might affect this change specific to our company/product. Post that, I'll analyse the external"See full answer

Linying W. - "Very helpful! But I have a question: the location of drivers can be changing every minute, so won't reading from location cache returning stale data?"See full answer

Anonymous Deer - "This interviewee had a decent framework but the specifics weren't impressive. I wouldn't post this as an example and would appreciate if you could replace this video."See full answer

John S. - "I have no idea if this would qualify, but I took a different, rather singular approach. Curious and gracious in advance for any and all feedback. My main question is whether this response goes into enough depth with regards to all the content types that Google Map stores, as I chose to focus uniquely on image storage (but am sure to state that clearly before I began): Clarifying questions: global map or US/sectional map? Assume global storage on a single end-user device? Yes consider co"See full answer

Suhasan C. - "I'm going to structure my answer like this so it is easy for both of us to follow up and grasp them easily. Let's first clear out some of the grey areas and make them black and white. Also, decide what are in-scope and out of scope. Second, let's understand what is our goal for improvement - is it the customer experience or any specific feature in mind? for a group of users? Third, I will brainstorm what are the pain points for user personas and solutions to improve them. Fourth, I will priorit"See full answer

Adam L. - "Discussed: Requirements of the system: latency language modality (assume keyboard typing) availability of data (assume cold start) success metric (accuracy of next word predicted?, or minimize false positives? -> accuracy to start) Data collection and processing: design ethical user experiments to collect typed out data design a simple tokenization strategy (word level encoding, character level encoding, byte-pair encodings, and discuss tradeoffs) collect data, and split"See full answer

Theodore (teddy) W. - "So here is what I would do if I had to designing a system to log messages in order involves several considerations, including the choice of software, hardware, storage mechanisms, and scalability. Here’s how I would approach this: 1. Requirements Analysis: Message Format: Define the structure of the messages to log (e.g., text, JSON). Volume: Estimate the expected volume of messages per second. This will help in determining the infrastructure requirements. **Order Guarantee"See full answer

Maritza C. - "First, I would make the following assumptions to solve this question without instant feedback. Assumptions: The main use cases for the refrigerator will be to maintain food in the right temperature and will not include making ice cubs or pouring water The only disability of the user is blindness Then, I would identify the main flows used when maintaining food refrigerated, which are: Putting food into the fridge Taking out food out of the fridge Within these flow these are som"See full answer

Chloe E. - "Here’s my general framework/formula/structure: Clarify - What do I need to know to make the question/prompt a little less ambiguous? What assumptions do I need to establish with the interviewer? Example: I would probably ask - Are we focused on professional/gig musicians who do music for a living? Or casual hobbyist musicians who make music for fun? Or I may want to know if I should focus on building on to a current Meta product like Instagram/FB Reels or think independently of th"See full answer

John F. - "Around mid-2023, I was tasked with investigating the feasibility of selling access to our site to third-party vendors who wanted to use bots to automate processes for their clients. Some initial work had been done on this but it was very high-level and very little data or analysis had actually been done. When I was tasked with this the idea was to sell access to a special header that would allow vendors to by-pass our F5 Shape implementation, a bot defense tool. From a business and security pers"See full answer

Harshita G. - "Is the "idea" I'm trying to sell something new or built off an existing service/product we offer? Interviewer: Let's assume new. Assuming it's a proper sit-down meeting with senior management to go over the proposal, here is what the slide deck would contain. Introduction/Description of the problem I'm trying to solve: Before proposing a solution, it is important to first identify the problem we're trying to solve.
